    Title. Effects of watering treatments on germination, survival, and growth of Rocky Mountain Douglas Fir: a greenhouse study. Title Variants: Alternative: Effects of watering treatments on germination, survival, and growth of Rocky Mountain Douglas Fir [Pseudotsuga menziesii glauca]: a . Place clean Douglas fir tips in a jar and cover with a decent quality gin, weigh down the needles to keep submerged. Infuse for weeks, strain and bottle. Douglas fir sugar: Place a few sprigs of clean and dry Douglas fir into a jar of organic cane sugar to infuse the sugar with its forest-y aroma. Use for baked goods or to coat the rim of.

    Pseudotsuga menziesii has two varieties: (a) Pseudotsuga menziesii var. menziesii, which is widespread in CA; (b) Pseudotsuga menziesii var. glauca, which grows in the Rocky Mountains. Leaves: Blue-green, growing on all sides of a twig or branch. Typically 1 inch ( cm) needles. Douglas-firs are evergreen. Douglas Fir Pseudotsuga menziesii Douglas firs are among the tallest trees on the continent, second only to coastal redwoods. They average from 45 to 60 metres in height, from to mm in diameter, and are found at elevations ranging from sea level to Size: 1MB.

Douglas-fir (Pseudotsuga menziesii) differs from balsam fir (Abies balsamea) in that: They are not in the same genus.

Lowry. Mycorrhizal and nonmycorrhizal container-grown Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) seedlings were outplanted on dry, burned-over sites in eastern Washington. Prior inoculation of seedlings did not significantly increase survival or height growth, but biomass increment during the first growing season was substantially by: Request PDF | Survival, and Growth Response of Douglas-Fir Trees to Increasing Levels of Bole, Root, and Crown Damage | We applied a range of bole and root damage treatments to young Douglas-fir.

Pseudotsuga menziesii is adapted to a fire regime with short to moderately long, fire-free Ps. menziesii is highly susceptible to low-severity fires, but the ability of Ps. menziesii to survive fire increases with California, the mean historic fire interval in these forests is from 5 to years.

Most California stands are on the higher end of this frequency range. Today Douglas- fir is also grown for Christmas trees.

Wildlife: The winged seeds are eaten by western squirrels, the red tree mouse, and the dusky-foot woodrat. The foliage and twigs are browsed by antelope, mule and white-tailed deer, elk, and mountain sheep. [Is the species highly domesticated. No] "The genus Pseudotsuga includes two species (P.

menziesii and P. macrocarpa) indigenous to North America and five species native to Asia. All except P. menziesii have a karyotype of 2N=24, the number of chromosomes characteristic of Pinaceae. But the Douglas-fir. Pseudotsuga menziesii is an evergreen conifer species in the pine family, is native to western North America and is known as Douglas fir, Douglas-fir, Oregon pine, and Columbian pine.

Despite its common name, it is not a true fir (i.e. it is not a member of the genus Abies).There are three varieties: coast Douglas-fir (P. menziesii var. menziesii), Rocky Mountain Douglas-fir (P Family: Pinaceae. Pseudotsuga / ˌ sj uː d oʊ ˈ t s uː ɡ ə / is a genus of evergreen coniferous trees in the family Pinaceae (subfamily Laricoideae).Common names include Douglas fir, Douglas-fir, Douglas tree, and Oregon pine.

Pseudotsuga menziesii is widespread in western North America and is an important source of timber. The number of species has long been debated, but two in western North America and Clade: Tracheophytes. Table 1.

Trees 5 to 6 feet ( cm) in diameter ( cm) and feet (76 m) or more in height are common in old-growth stands [].These trees commonly live more than years and occasionally more than 1, Douglas-fir ranks as the second most important softwood in New Zealand, after radiata pine, and occupies about 5% of the total plantation forest area.

Discussion of Phylogenetic Relationships. Farjon () recognized only four species of Pseudotsuga: Pseudotsuga macrocarpa from southern California, Pseudotsuga menziesii ranging from Canada to south-central Mexico, Pseudotsuga japonica from southern Japan, and Pseudotsuga sinensis from China.

Included in the ToL phylogeny is also P. wilsoniana from Taiwan. Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) seed-lings from three nurseries in the Pacific Northwest United States were lifted on five dates from mid-October through mid-December Each nursery provided seedlings from a low- and a high-elevation seed lot.
